Description

Technical Field

[0001] The utility model belongs to the technical field of automobile collision occupant protection systems, and specifically relates to a vehicle and its safety airbag system, and an occupant safety protection system. Background Art

[0002] As the consumer market places increasingly higher demands on the automotive industry and the requirements for smart cockpits and seat comfort gradually increase, zero-gravity seats based on the combination of zero-gravity principles and passenger car seat technology have gradually attracted more consumers as high-energy configurations. They can achieve a large-angle reclining adjustment of the passenger seat, making the support pressure on the waist, hips and legs more even, and providing better riding comfort.

[0003] In this case, when a vehicle collision occurs, especially a head-on collision, the seat cushions and safety belts in a zero-gravity state provide poorer restraint for the occupants than those sitting in the entire vehicle, and the occupants may easily dive down, making it impossible for the seats, safety belts and airbag system to work in coordination to provide the most effective protection. When a side collision occurs and the occupants are lying flat, although the occupants' torsos are protected by side airbags, the deployment height of ordinary side airbags cannot cover the occupants' heads, which may easily cause a hard collision between the head and the vehicle interior and cause serious injuries. Utility Model Content

[0004] In view of the above shortcomings of the prior art, the purpose of the utility model is to provide a vehicle and its airbag system, and an occupant safety protection system to improve the problem that when a vehicle collision occurs, especially a head-on collision accident, the occupants are prone to diving, the seats, seat belts and airbag systems cannot work together to provide the most effective protection, and the ordinary side airbags are not deployed to a height that covers the occupants' heads, which can easily cause a hard collision between the head and the vehicle interior and cause serious injuries.

[0005] To achieve the above-mentioned purpose and other related purposes, the utility model provides a vehicle airbag system, which includes:

[0006] Zero-Gravity Seating System;

[0007] The airbag assembly includes a front airbag facing the zero-gravity seat system, a side airbag located on the side of the zero-gravity seat, and a side air curtain located on the upper side beam of the vehicle. The side air curtain includes a first protection zone and a second protection zone after deployment. The first protection zone corresponds to the head position of the occupant in a normal sitting position, and the second protection zone corresponds to the head position of the occupant in a zero-gravity state.

[0008] In one embodiment of the present invention, the height of the second protection zone is greater than the height of the first protection zone, and the lower edge of the second protection zone protrudes toward the bottom of the vehicle relative to the lower edge of the first protection zone.

[0009] In one embodiment of the present invention, the side air curtain further includes a third protection zone, and the third protection zone corresponds to the head position of the rear occupant of the vehicle.

[0010] In one embodiment of the present invention, a pelvic restraint airbag is further included, and the pelvic restraint airbag is arranged at the seat cushion position of the zero-gravity seat system.

[0011] In one embodiment of the present invention, after the pelvic restraint airbag is deployed, it is arranged obliquely upward from the seat cushion in a direction away from the backrest of the zero-gravity seat system.

[0012] In one embodiment of the utility model, a control system is also included, which is electrically connected to the airbag assembly and is used to control the detonation and deployment of the front airbag, the side airbag, the side air curtain and the pelvic restraint airbag.

[0013] The utility model also provides a vehicle occupant safety protection system, comprising:

[0014] An airbag system as described in any one of the above embodiments;

[0015] Occupant occupancy monitoring system, which monitors the size, weight and seat belt wearing of occupants;

[0016] Seat posture detection system, which monitors the fore-aft position, seat cushion angle and backrest angle of the zero-gravity seating system;

[0017] an integrated seatbelt system for restraining occupants at any angle;

[0018] The occupant protection restraint control system is used to output a detonation signal of the integrated seat belt system to tighten the seat belt when the vehicle collides, and to output a detonation signal of the airbags at different positions in the airbag system to detonate and deploy the airbags.

[0019] In one embodiment of the present invention, the zero-gravity seat system is a collapsible energy-absorbing connecting rod structure.

[0020] In one embodiment of the present invention, the occupant protection restraint control system is connected to the occupant occupancy monitoring system, the seat posture detection system, the airbag system and the integrated seat belt system through both CAN lines and hard lines.

[0021] The utility model also provides a vehicle, comprising the vehicle occupant safety protection system as described in any one of the above embodiments.

[0022] The utility model proposes a vehicle and its airbag system, and an occupant safety protection system. Through specially designed side air curtains, a first protection zone is formed after deployment to protect the occupant's head position in a normal sitting position, and a second protection zone is formed to protect the occupant's head position when the occupant is in a zero-gravity state.

Together with the side air curtains and other airbags, the protection effect can be effectively improved.

[0023] The utility model proposes a vehicle and its airbag system, and an occupant safety protection system. An integrated safety belt system installed on the seat ensures that the safety belt can be used when the zero-gravity seat is at any angle, effectively restrains the occupant, improves the sense of security when riding, and improves the occupant protection performance under large-angle postures. In conjunction with pelvic restraint airbags, side air curtains and other airbags, the protection effect can be effectively improved.

[0030] The following is an explanation of the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0031] It should be noted that the illustrations provided in this embodiment are only used to schematically illustrate the basic concept of the present invention. Therefore, the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0032] See also Figures 1 to 4 As shown, the utility model proposes a vehicle and its airbag system, and a passenger safety protection system, so as to improve the problem that when a vehicle collision occurs, especially a frontal collision accident, the passenger is prone to diving, the seat, seat belt and airbag system cannot coordinate to play the most effective protection, and the ordinary side air curtain cannot cover the head of the passenger, which easily causes the head to collide with the interior of the vehicle and cause serious injuries. Specifically, the vehicle airbag system includes a zero-gravity seat system 10 and an airbag assembly, and the airbag assembly includes a front airbag 20, a side airbag 30 and a side air curtain 40, wherein the front airbag 20 is directly opposite to the front of the zero-gravity seat system 10, the side airbag 30 is located on the side of the zero-gravity seat system 10, and the side air curtain 40 is located at the upper side beam of the vehicle. When the vehicle collides, the front airbag 20, the side airbag 30 and the side air curtain 40 are ignited and deployed to effectively support and cushion the chest, torso side and head of the passenger, thereby playing a protective role.

[0033] See also Figure 2 and Figure 3As shown, in the present embodiment, the side air curtain 40 after being ignited and deployed includes a first protection zone 41, a second protection zone 42 and a third protection zone 43. The first protection zone 41 corresponds to the head position of the occupant in a normal sitting position, and is used to protect the head of the occupant in a normal posture. The second protection zone 42 corresponds to the head position of the occupant in a zero-gravity state, and is used to protect the head of the occupant in a zero-gravity state. The third protection zone 43 corresponds to the head position of the rear passengers of the vehicle, and is used to protect the safety of the rear passengers of the vehicle.

[0034] See also Figure 2 and Figure 3 As shown, in the present embodiment, the height of the second protection zone 42 is greater than the height of the first protection zone 41, and the lower edge of the second protection zone 42 protrudes toward the bottom of the vehicle relative to the lower edge of the first protection zone 41, and the side air curtain 40 is arranged at the upper side beam of the vehicle, and the deployed air curtain airbag is lengthened to fully cover the occupants in normal posture and zero-gravity posture. When the vehicle is subjected to a side collision, the detonated side air curtain can effectively protect the occupants' heads and reduce head injuries.

[0035] See also Figure 1 and Figure 4 As shown, in this embodiment, the airbag assembly also includes a pelvic restraint airbag 50, which is arranged at the seat cushion position of the zero-gravity seat system 10. The pelvic restraint airbag 50 can be detonated and deployed when the vehicle collides, preventing the occupant's torso from sliding along the seat back, preventing the occupant from diving, reducing chest rib compression injuries, buffering and absorbing collision energy, and reducing spinal injuries. In this embodiment, after the pelvic restraint airbag 50 is deployed, it is arranged obliquely upward from the seat cushion of the zero-gravity seat system 10 to the direction away from the back of the zero-gravity seat system 10, so that it presents an angle, which can further prevent the occupant's torso from sliding along the seat back and preventing the occupant from diving. It can effectively improve the protection effect by cooperating with the side air curtain 40 and other airbags.

[0036] See also Figure 1 As shown, in this embodiment, the airbag assembly also includes a control system, which is electrically connected to the airbag assembly and is used to control the detonation and deployment of the front airbag 20, the side airbag 30, the side air curtain 40 and the pelvic restraint airbag 50, thereby ensuring the safety of the occupants.

[0037] See also Figures 1 to 4As shown, the utility model also proposes a vehicle occupant safety protection system 100, which includes the airbag assembly, occupant occupancy monitoring system 110, seat posture detection system 120, integrated seat belt system 130 and occupant protection restraint control system 140 described in the above embodiments, wherein the zero-gravity seat system 10 described in the above embodiments can provide the occupants with the best comfortable riding experience, and the seat is one of the restraint systems with the longest contact time with the occupants and the most direct contact time, so its safety performance is particularly important. The zero-gravity seat system in this embodiment adopts a collapsible energy-absorbing connecting rod structure, which effectively protects the safety of the occupants by adopting a non-maximum angle connecting rod mechanism for adjustment.

[0038] See also Figures 1 to 4 As shown, in this embodiment, the occupant occupancy monitoring system 110 is used to identify the occupant's body shape, weight and other information, and to monitor whether the occupant is wearing a seat belt. If the occupant is not wearing a seat belt, the occupant protection restraint control system outputs a signal to give an audible and visual warning to remind the occupant to wear a seat belt.

[0039] See also Figures 1 to 4 As shown, in this embodiment, the seat posture detection system 120 is used to monitor the front and rear position, seat cushion angle and backrest angle of the zero-gravity seat system. Specifically, when there is an occupant sitting on the seat, the front and rear position, seat cushion angle, backrest angle, etc. of the seat are detected by multiple sensors such as position sensors and angle sensors, assisted by the occupant body shape, weight and other information monitored by the occupant occupant monitoring system 110, to determine when a collision occurs, the front airbag 20, side airbag 30, side air curtain 40, pelvic restraint airbag 50 and integrated seat belt system 130 in the airbag assembly delay detonation time.

[0040] See also Figures 1 to 4 As shown, in this embodiment, the integrated seat belt system 130 is used to restrain the occupant at any angle. It can be used when the zero-gravity seat is at any angle, effectively restrain the occupant, improve the sense of security when riding, and improve the occupant protection performance at a large angle. When a collision accident occurs, the occupant protection restraint control system 140 outputs a corresponding detonation signal according to the algorithm matching, detonates the pre-tightening function of the retractor of the seat belt, and effectively restrains the occupant on the seat. It can be understood that the integrated seat belt system 130 installed on the seat ensures that the seat belt can be used when the zero-gravity seat is at any angle, effectively restrains the occupant, improves the sense of security when riding, and improves the occupant protection performance at a large angle. The protection effect can be effectively improved in conjunction with the front airbag 20, the side airbag 30, the side air curtain 40, the pelvic restraint airbag 50 and other airbags.

[0041] See also Figures 1 to 4As shown, in this embodiment, the front airbag 20 is used when the vehicle has a head-on collision. The occupant protection restraint control system 140 outputs a corresponding detonation signal according to algorithm matching to detonate the front airbag 20, which can effectively support and cushion the occupant's head and chest and play a protective role.

[0042] See also Figures 1 to 4 As shown, in this embodiment, the side airbag 30 is used when the vehicle has a head-on collision. The occupant protection restraint control system 140 outputs a corresponding detonation signal according to algorithm matching to detonate the side airbag 30, which can effectively support and cushion the occupant's torso and play a protective role.

[0043] See also Figures 1 to 4 As shown, in this embodiment, the side air curtain 40 is arranged at the upper side beam of the vehicle, and the air curtain airbag is lengthened after deployment, which can fully cover the occupants in normal posture and zero-gravity posture. When the vehicle is hit, the side air curtain after detonation can effectively protect the occupants' heads and reduce head injuries.

[0044] See also Figures 1 to 4 As shown, in this embodiment, after a head-on collision of the vehicle occurs, the pelvic restraint airbag 50 can be detonated by the occupant protection restraint control system according to algorithm matching, thereby preventing the occupant's torso from sliding along the seat back, preventing the occupant from diving, reducing chest rib compression injuries, cushioning and absorbing collision energy, and reducing spinal injuries. Together with the side air curtains 40 and other airbags, the protection effect can be effectively improved.

[0045] See also Figures 1 to 4 As shown, in this embodiment, the occupant protection restraint control system 140 is used to output the detonation signal of the integrated seat belt system to tighten the seat belt when the vehicle collides, and output the detonation signal of the airbags at different positions in the airbag system to detonate and deploy the airbags. For example, the occupant protection restraint control system 140 stores the optimal protection parameters adapted to the complex matrix of different body types, different sitting positions and different angles, and different collision conditions, such as the detonation parameters of the front airbag 20, the side airbag 30, the side air curtain 40, the pelvic restraint airbag 50, and the integrated seat belt system 130, and detonates the seat belt and each airbag in the airbag assembly according to the detonation parameters, so that the front collision and side collision occupant protection safety system can play the best protection effect. It can be understood that the control system described in the above embodiment can be a functional module of a part of the occupant protection restraint control system 140, which is integrated with the control modules of other components.

[0046] See also Figures 1 to 4As shown, in this embodiment, the occupant protection restraint control system 140 is connected to the occupant occupancy monitoring system 110, the seat posture detection system 120, the airbag system and the integrated seat belt system 130 through both CAN lines and hard lines, ensuring that the system can output signals under various extreme collision conditions, ensuring the stability of the system, and effectively improving the reliability of the occupant safety protection system.

[0047] See also Figures 1 to 4 As shown, in this embodiment, the control process of the above-mentioned occupant safety protection system 100 is as follows:

[0048] The occupant occupancy monitoring system 110 is used to monitor and obtain personal information of the current occupant, such as body shape and weight. Of course, the occupant occupancy monitoring system 110 is also used to monitor whether the occupant is wearing the seat belt. If the seat belt is not worn, the occupant protection restraint control system 140 outputs a signal to give an audible and visual warning to remind the occupant to wear the seat belt, so as to ensure that the occupant wears the seat belt, thereby ensuring that the occupant safety protection system 100 of the vehicle plays its due role in protecting the safety of the occupants in the event of a collision.

[0049] The current position information of the zero-gravity seat system 10 is detected by the seat posture detection system 120, and the front and rear position of the seat, the seat cushion angle, and the backrest angle are detected by multiple sensors such as position sensors and angle sensors;

[0050] The occupant protection and restraint control system 140 obtains the personal information of the current occupant monitored by the occupant occupant positioning monitoring system 110 and the position information of the zero-gravity seat system 10 detected by the seat posture detection system 120, and determines, based on the personal information of the occupant and the position information of the seat, the detonation parameters of the front airbag 20, the side airbag 30, the side air curtain 40, the pelvic restraint airbag 50 and the integrated seat belt system 130, such as the delayed detonation time, when a collision occurs. In this embodiment, the occupant protection and restraint control system 140 pre-stores personal information of different types of occupants, seat position information, and the integrated seat belt system 130 and detonation parameters of the airbag assembly adapted thereto. When necessary, the occupant protection and restraint control system 140 can directly match the occupant's personal information and seat position information to obtain the corresponding detonation parameters, and send them to the front airbag 20, the side airbag 30, the side air curtain 40, the pelvic restraint airbag 50 and the integrated seat belt system 130, so as to control the detonation of the integrated seat belt system 130 to restrain the occupant to the seat, and control the detonation and deployment of one or more of the front airbag 20, the side airbag 30, the side air curtain 40, and the pelvic restraint airbag 50, so as to protect the safety of the occupants.

[0051] It can be understood that in this embodiment, the occupant protection restraint control system 140 is designed to output the corresponding detonation parameters of the front airbag 20, the side airbag 30, the side air curtain 40, the pelvic restraint airbag 50 and the integrated seat belt system 130, so as to control the detonation and deployment of the airbag and the seat belt to achieve the best protection for the occupants. At the same time, the occupant protection restraint control system is connected to other systems through CAN lines and hard lines to achieve dual connection interaction, ensuring that the system can output signals in various extreme collision situations, ensuring the stability of the system, and effectively improving the reliability of the vehicle's occupant safety protection system.

[0052] The utility model also provides a vehicle 200, which includes the vehicle occupant safety protection system 100 described in the above embodiment, which will not be described in detail here to avoid repetition. It can be understood that the vehicle occupant safety protection system 100 can be widely used in the design of a collision occupant protection safety system for a zero-gravity seat of a passenger car, has a wide range of applications, high reliability, and can effectively improve the safety of occupants in the vehicle.
